The axisymmetric elastic waves propagation in the wall of an infinite single-layered solid of revolution

The elastic waves in an infinite axisymmetric single-layered cylindrical pipe have been considered. An approximate analytical solution of dispersion equation for a thin-walled cylindrical pipe and an exact one for a cylindrical pipe with an optional wall thickness were given. The latter solution was obtained using some particular parameter values. The results were interpreted in terms of physics.
